    "title": "drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure",
    "summary": "In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure When drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo is not freed. Add xe_bo_free(storage) before returning the error. xe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on error. Therefore, xe_dma_buf_init_obj() must also free the bo on its own error paths. Otherwise, since xe_gem_prime_import() cannot distinguish whether the failure originated from xe_dma_buf_init_obj() or from xe_bo_init_locked(), it cannot safely decide whether the bo should be freed. Add comments documenting the ownership semantics: on success, ownership of storage is transferred to the returned drm_gem_object; on failure, storage is freed before returning. v2: Add comments to explain the free logic. (cherry picked from commit 78a6c5f899f22338bbf48b44fb8950409c5a69b9)",
